 - **Numeric parsing should stay on the shared portable helpers.** Route JSON/XML/KeyValue/import numeric decoding through the `Core.tryParse...Invariant` and `Core.parse...Invariant` helpers instead of ad hoc `Parse(..., InvariantCulture)` calls plus exception-type checks, so Fable stays warning-free and the invalid/out-of-range behavior remains aligned across runtimes.
 - **The C# facade is intentionally narrower than the bridge.** `CSharpSchema.Record(...)` is for new setter-bound C# classes and wraps the existing schema model; constructor-bound or attribute-driven C# contracts should still prefer the bridge or future codegen instead of stretching the facade into a second schema system.
 - **Do not use `System.Enum.ToObject` or `System.Convert.ChangeType` in the core portable path.** Fable rejects both APIs. When adding enum support, keep the .NET path behind `#if !FABLE_COMPILER` and use a Fable-safe erased-number path instead.
-- **BenchmarkDotNet now runs via the in-process emit toolchain.** This avoids child-project generation conflicts with the archived experimental clone under `benchmarks/CodecMapper/`, which also contains a `CodecMapper.Benchmarks.fsproj`. Keep the manual runner for quick snapshots and README numbers.

 - **Project layout is now split by role.** Public libraries live under `src/`, executable and xUnit tests live under `tests/`, and benchmark apps live under `benchmarks/`. Keep new projects in the root that matches their purpose so tooling and docs discovery stay predictable.

 ## Benchmarking Notes
 
 - `benchmarks/CodecMapper.Benchmarks/CodecMapper.Benchmarks.fsproj` is now a runnable BenchmarkDotNet app again (`OutputType=Exe` plus a real entrypoint), so the failure is no longer at the top-level `dotnet run` step.
-- The archived experimental clone under `benchmarks/CodecMapper/` also contains a `CodecMapper.Benchmarks.fsproj`, which makes BenchmarkDotNet's default child-project generator ambiguous once both repos exist in the same workspace.
 - `benchmarks/CodecMapper.Benchmarks/Program.fs` now forces BenchmarkDotNet onto `InProcessEmitToolchain` to avoid child-project generation entirely.
 - The remaining warning during local runs is just Linux process-priority elevation failure (`Permission denied`), which does not stop benchmarks from executing.
 - A manual Release runner was added in `benchmarks/CodecMapper.Benchmarks.Runner` to keep benchmark reporting moving while that tooling issue remains unresolved.

 ## Legacy CodecMapper Comparison
 
-- The previous `CodecMapper` repo is cloned locally at `benchmarks/CodecMapper/` for reference only and is ignored by this repo's Git metadata.
 - Its published benchmark snapshot is not directly comparable to `CodecMapper`'s current README numbers because it benchmarks a 1000-record `Person list` payload, while `CodecMapper` currently publishes a small single-object benchmark.
 - The old repo also fails to complete BenchmarkDotNet runs cleanly on this machine under `.NET SDK 10.0.103`; direct child-project builds still end with `Build FAILED` and `0 Error(s)`.
 - Legacy branding assets from the archived experimental repo are preserved under `notes/legacy-codemapper/`.
